Arjen Robben and Philipp Lahm are racing to be fit for Wednesday's top-of-the-table tussle with RB Leipzig. Both players sat out the weekend's narrow win at SV Darmstadt 98, but returned to training on Monday – Robben joined up with the squad, while Lahm worked individually. If they fail to recover in time, Xabi Alonso and Rafinha should keep their places in the starting line-up. Douglas Costa, in spite of his stunning winner against Die Lilien, is likely to start on the bench.
